The electric overhead garage door opener was invented by C.G. Johnson in 1926 in Hartford City, Indiana. Contrary to popular belief, the electric opener does not provide the actual lifting power to open and close a heavy garage door. Instead, most of the actual lifting power comes from the counterbalance springs that are under tension to lift the garage door via steel counterbalance cables. The electric opener only controls how far the door opens and closes, as well as the force the garage door exerts. In most cases, the garage door opener also acts as a lock.

The typical electric garage door opener consists of a power unit that contains the electric motor. The power unit attaches to a track. A trolley connected to an arm that attaches to the top of the garage door slides back and forth on the track, thus opening and closing the garage door. The trolley is guided along the track by a chain, belt, or screw that turns when the motor is operated. A quick-release mechanism is attached to the trolley to allow the garage door to be disconnected from the opener for manual operation during a power failure or in case of emergency. Limit switches on the power unit control the distance the garage door opens and closes once the motor receives a signal from the remote control or wall push button to operate the door.

You are correct, there is always a chance they could be stuck out in the sun but if so, what is problem? It is sunny and no damage will occur.

The danger is if the awnings are out in heavy wind in which case the arms could break – I have never had an instance of this in dealing with awnings in 10 years – not related to being stuck open by a powercut.

You seem to be quite confident with the electrical awning but my feeling is that it could get stuck anytime. Why it won’t when it is sunny? I understand that it could have some problems during bad weather period but why not during sunny period?

I have been wanting a sun awning for my back deck for a while now. Can you suggest some good companies to buy from? This was a good review by the way.
